RUBBER SOLE-FRGEELTQE BJGTS AND SE13.

To (ZZZ whom may condemns:

Be it known that l, Eocene FULLER, citizen of the United States, residin'et Providence, in. the county of Frovi once and State of Rhode island,have invented.-

edge part of the sole proper and terminates at the shank portion; andhaving the half sole member provided with means for mainmining it inposition on the sole, and further, having a yieldable packing positionedsoas to exclude or prevent the entrance of water between the adjacentsurfaces of the sole and helfsole members, all as more fully hereinaiterset forth and claimed.

The object 1 have in view is toprovide a simple, connect, inexpensive,easily and quickly applied article of footwear, which may be termed adetachable rubber ball"- sole, adapted to protect the bottom of theusual more or less pervious sole portion of boots and shoes from contactwith wet or moist surfaces and thus prevent the absorption. orpenetration oi moisture therethrough, while at the same time in no wiseinterfering with the usual ventilation or circulation or air through theupper portion or such boots and shoes. l

In order to increase the durability and eificiency df the device, Iprefer to make its normal form in a. long tudinal direction such that inapplying it to the sole of the shdeit will necessarily be flattenedsomewhat, thereby, too, increasing its resiliency and holding capacity,and also producing a smallair 'space of cushioning chamber between theadjacent surfaces.

In the accompanying sheet of drawings, Figure 1 represents a partialside elevation of a shoe, showing (sectionally) my improved rubbersole-protector removably attached to the sole thereof, as in use. F ig.2 is a side elevation of the device, as a whole, detached from the shoe.Fig. 3 is a correspending top plan view. Fig.4 is a longitudinalsectional view, in enlarged scale,

again referring to the rewings, desighates the invention or e-rticle ofmanufacture as a whole, which me be termed an impervious, resilient helsole, adapted to be detachably secured to the usual sole proper, o, of aboot or shoe, and having its rear end provided with a suitable clasp orclamp, as c, or other analogous holding ineans, c0nstructed to engagethe usual shank portion, e, integral with said sole part e. The saidhalf-sole member is quite shallow, and preferably made from rubber or acomposition of rubber, molded and vulcanized in any suitable orwell-known manner; its normal form being substantially as represented inFigs. 2

and 3. Thesole'part, a, is or may be pram-- tically uniform in thicknessthroughout, and provided with an inner lined surface and roughened outerbottom surface, substantially as employed in rubber overshoes, and(which is very importent) is advantageously of abnormal, i. 0., deepcurvature (as clearly ,shown in Fig. 2). l'have discovered by ex-"periments and tests that, by constructing the sole (2 .with saidabnormal curvature, the following advantages accrue: (l), When thehalf-sole is-in use on a shoe'sole, the abnormal. curvature permits theformation of an air'chamber s between the half-sole and the shoe-sole,which prevents sweating of the foot, inherent in the use of half-solesand rubber overshoes of ordinary construction, and (2) the bead a will,in use, be caused to adhere more snugly to theupper edge of the leathersole. The outer peripheral edge of the sole or is extended upward andforms a. comparatively thin, narrow side wall, a, terminating at the topin an inwardly projecting beaded or thickened free edge part, athelatter being shown sectionally in Fig.

Fig. 5 is a front r; and

1. The rear end portion of member A isv adapted to engage the shank orarch part, a of a shoe, and is provided with a norm pressible,transverserib or packing member;.
